Serum Levels of Interleukin 33 and Soluble ST2 Are Associated with the Extent of Disease Activity and Cutaneous Manifestations in Patients with Active Adult-onset Still’s Disease

TLDR
Results indicate that the IL-33/ST2 signaling pathway may play a role in the pathogenesis of the acute inflammation and skin manifestations associated with AOSD.
Abstract
Objective Interleukin 33 (IL-33), a member of the IL-1 family and a ligand of the orphan receptor ST2, plays key roles in innate and adaptive immunity. We examined the associations between IL-33/ST2 levels and clinical manifestations of patients with active adult-onset Still’s disease (AOSD). Methods Blood samples were collected from 40 patients with active AOSD, 28 patients with rheumatoid arthritis (RA), and 27 healthy controls (HC). The serum levels of IL-33 and soluble ST2 were determined using ELISA. Expression levels of IL-33 and ST2 in biopsy specimens obtained from 34 AOSD patients with rash were immunohistochemically investigated. Results IL-33 levels of patients with AOSD were higher than those of patients with RA and HC. Soluble ST2 levels of patients with AOSD were higher than those of HC, but not of patients with RA. Serum IL-33 levels correlated with systemic score, erythrocyte sedimentation rate, ferritin levels, and aspartate transaminase levels. However, serum soluble ST2 levels correlated only with ferritin levels. The numbers of inflammatory cells expressing IL-33 and ST2 were elevated in skin lesions of patients with AOSD compared to HC, but did not differ from those of the skin lesions of eczema or psoriasis. Conclusion We found significantly higher serum IL-33 and soluble ST2 levels in patients with active AOSD. Results indicate that the IL-33/ST2 signaling pathway may play a role in the pathogenesis of the acute inflammation and skin manifestations associated with AOSD.

Interleukin-33 modulates inflammation in endometriosis

TL;DR: Collectively, these results provide convincing evidence that IL-33 perpetuates inflammation, angiogenesis and lesion proliferation, which are critical events in the lesion survival and progression of endometriosis.

Long-Term Retention Rate of Anakinra in Adult Onset Still's Disease and Predictive Factors for Treatment Response.

TL;DR: Long-term DRR of ANA has been found excellent and is not affected by different lines of biologic treatment, concomitant use of cDMARDs, or type of AOSD, while the typical skin rash was negatively related with ANA withdrawal owing to long-term remission.

Alarmins HMGB1, IL-33, S100A7, and S100A12 in Psoriasis Vulgaris.

TL;DR: The alarmins HMGB1, IL-33, S 100A7, and S100A12 were significantly elevated in the serum of patients, which states the hypothesis that they play specific roles in the immunopathology of psoriasis.

IL-33 in Rheumatic Diseases.

TL;DR: The role of the IL-33/serum stimulation-2 axis in rheumatic diseases has been extensively studied in recent years as mentioned in this paper, and the dual role of IL33/ST2 axis has been shown to have a detrimental effect on rheumatoid arthritis, systemic lupus erythematosus, and other RML diseases.

IL-33, an interleukin-1-like cytokine that signals via the IL-1 receptor-related protein ST2 and induces T helper type 2-associated cytokines

TL;DR: A member of theIL-1 family, IL-33, which mediates its biological effects via IL-1 receptor ST 2, activates NF-kappaB and MAP kinases, and drives production of T(H)2-associated cytokines from in vitro polarized T( H)2 cells is reported.

Preliminary criteria for classification of adult Still's disease.

TL;DR: Classification criteria for adult Still's disease was attempted by analyzing the data obtained through a multicenter survey of 90 Japanese patients with this disease and of 267 control patients and the proposed criteria consisted of fever, arthralgia, typical rash, and leukocytosis as major criteria.

The IL-1-Like Cytokine IL-33 Is Constitutively Expressed in the Nucleus of Endothelial Cells and Epithelial Cells In Vivo : A Novel ‘Alarmin’?

TL;DR: It is speculated that IL-33 may function, similarly to the prototype ‘alarmin’ HMGB1, as an endogenous ‘danger’ signal to alert the immune system after endothelial or epithelial cell damage during trauma or infection.
